The Japanese eatery is often described as Sydney's most exclusive restaurant because only members, which include those who attend an "orientation", can make bookings.

But in an announcement posted online, Ichikawa said Wafu would close in the coming months partly because not enough diners were willing to abide by her policies.

"First, many potential customers, and even some members, have entered Wafu without doggie containers," she wrote on the Wafu website.

I found it distressing when, after eating, with obvious self-satisfaction, people said, 'SO FULL!'. Perhaps this was meant as a compliment, but to me it meant that the utterer had deliberately damaged their body

"I could not accept such inconsiderate people. The refusal of this most simple, basic request shows that Wafu's ways are not respected. Intolerable.

"Further, I found it distressing when, after eating, with obvious self-satisfaction, people said, 'SO FULL!'.

"Perhaps this was meant as a compliment, but to me it meant that the utterer had deliberately damaged their body by wasting food through over-eating.

"It meant also that the utterer did not understand Wafu's ways, and had not bothered to make the effort or take time to find out what these are.

"Wafu is viable, as a business, if I continue to accept inconsiderate, greedy people.

"But I couldn't do it. Wafu has always been, and will remain, more to me than simply just another business."

Ichikawa also wrote that the "ongoing global economic crises" played a part in her decision, as well as "the disheartening effect of seeing people walking whilst cramming fast-food in jaws that cannot even chew".

The chef said Wafu's doors would remain open to members, or anyone willing to bring their own containers, while the restaurant is up for sale.

She said Wafu would be "re-structured" and a new, smaller Wafu may be set up at some point.
